I downloaded dcef3 and found some demos in it. I copied contents of "src" directry to "minimal" directory and it worked fine. But when I do this to guiclient directory, I get error while opening the project:
Class TChromium not found
How can I fix this error?
OK I solved this regarding to this answer: How do I install the Chromium package in Delphi?
I opened the project "minimal"
Right-clicked "cefclient" on the project manager
Clicked "Install"
Now I'm able to open the other demo (gui project)
